Title: Ink jet printer
IPC: B41J2/12
Filed: 1973-05-14
Abstract: 1405197 Ink drop printers INTERNATIONAL BUSINESS MACHINES CORP 14 May 1973 [27 June 1972] 22760/73 Heading G4H An ink-drop printer 1-30 comprises means 37-57 for detecting failure in synchronisation between drop charging and drop formation. Test signals 41-43, 81 or 65 (ramp or pulse signals, Fig. 3, not shown) are applied to the charge electrode 18 so as to cause otherwise uncharged drops to be deflected into a gutter 35 or 36; the synchronization may be effected line-by-line (e.g. in the home position for each line), between characters or within the matrix boundaries of individual characters. Each gutter contains a sensor which translates charge into current level; the use of gutter 35 produces current levels smaller than those normally encountered during printing, whereas the levels obtainable from gutter 36 are higher since a greater potential is required to deflect the drops thereto (this can also detect lack of potential 25 on deflecting plate 22). The resulting signal A or B is changed to a voltage level and fed with a reference 55 to a comparator 57, the resulting difference signal being used to adjust the timing of drop separation in a piezo-electric crystal driver 15 relative to the signals applied to charge electrode 18. Another embodiment similar to that of Fig. 1 is described with reference to Fig 2 (not shown). Co-pending Application No. 41107/73 describes a similar system for a plurality of ink streams.

Abstract: 1,108,703. Oil-extended polymers of 1,3-butadiene. ASAHI KASEI KOGYO KABUSHIKI KAISHA. 29 July, 1966 [5 Aug., 1965], No. 34111/66. Heading C3P. Oil-extended polymers are prepared by generating free radicals in a solution of a polymer or copolymer in an inert solvent thereby cross-linking the polymer or copolymer and then removing the inert solvent, the polymer or copolymer being formed by solution polymerization of 1,3-butadiene, the copolymer (if present) containing at least 50% by weight of 1,3-butadiene units, and the said inert solvent solution containing 5 to 300 parts by weight of a process oil per 100 parts by weight of the polymer or copolymer. The preferred copolymer is a butadiene-styrene copolymer. A Ziegler-type catalyst or a lithium-based catalyst is preferably used in the solution polymerization. The free radicals may be generated in solution by adding peroxides as free radical generators and heating the solution. Maleic anhydride, maleic acid or divinylbenzene may be used as cross-linking assistants for the peroxide. The process-oil may be a paraffinic, naphthenic or aromatic hydrocarbon having a viscosity-gravity constant of 0-79-1-00. Other free radical generators are azo compounds and compounds which generate radicals under ultra-violet light or γ-radiation. Inert solvents used in the examples are nhexane and toluene. Free radicals generators used are benzoyl peroxide, lauroyl peroxide, azobis-isobutyronitrile, diphenyl disulphide as photo-sensitizer irradiated with ultraviolet light, dicumyl peroxide and p-methane hydroperoxide. A butadiene-isoprene copolymer is used in Example 13. Catalysts used in the preparation of the polymers are n-butyl, sec.- butyl and iso-butyl lithium, 1,2-dilithiostilbene, triethyl aluminium / boron trifluoride / nickel naphthenate, triethyl aluminium / titanium tetrachloride/iodine. The oil-extended polymers may be cured and compounded using sulphur, N-cyclohexyl-2-benzothiazole sulphenamide, stearic acid, zinc oxide, phenyl-#-naphthylamine, carbon black, an aromatic process oil, dibenzothiazole disulphide, diphenyl guanadine; silicic anhydride and 2,6-ditertiary butyl hydroxytoluene.

Title: Improvements in joints for wrought metal tubes
IPC: F16L23/028
Filed: 1923-09-12
Abstract: 223,371. Bromford, Ltd., and Reimann, J. Sept. 12, 1923. Butt joints. - In wrought metal tubes of the kind provided with integrally formed external flanges or collars adapted to be engaged by loose coupling members upon the tubes, the shoulder is formed by turning the end of the tube back upon a liner or sleeve A located on the outside of the tube B. The liner A fits closely around the tube B, and, when the fold B<2> is made, the latter is firmly compressed upon the liner. The exposed end A<3> of the liner may be welded to the tube and to the fold by providing a liner which is shorter than the fold and filling the channel formed thereby with brazing or welding metal, or by providing a fillet of welding metal around the shoulder formed by the liner and tube end to form an inclined face against which the coupling member will bear. The jointing face B<4> formed at the fold may be either substantially fiat, or rounded owing to the folding action; or it may be formed with a concave face so as more effectually to retain the joint ring, the adjacent end of the liner being correspondingly shaped in each case. Specification 195,219 is referred to.

Title: Information Storage.

IPC: G11C13/04

Abstract: 1,188,976. Optical apparatus. EASTMAN KODAK CO. May 18, 1967 [May 18, 1966; March 28, 1967], No.23182/67. Heading G2J. The invention relates to a method and apparatus for recording digital data on photographic film 24 in the form of a plurality of superimposed diffraction grating patterns. Coherent light, preferably from a laser 10, is spread by lenses 11, 12 and reflected by mirrors 13, 14a-14g to give a reference beam (from the mirror 13) and seven signal beams each of which interfere with the reference beam to form seven superimposed stationary line grating patterns on a recording area 21 of the film 24. This may be taken to correspond to a particular binary numeral, e. g. 1111111. To record a different binary numeral one of the digits must be changed to 0, and this can be done by omitting one of the grating patterns. Each mirror is mounted on a control device 15a- 15g responsive to appropriate signals from circuitry 17, In one embodiment of a control device, Fig. 5 (not shown) each mirror is supported on a Piezo-electric crystal and when one of the patterns is to be omitted, the appropriate crystal is energized so as to deflect the mirror and its signal beam away from the recording beams. Preferably the mirrors are moved in cyclical or quasi-cyclical motion so as to smear the corresponding grating patterns across the recording area to make sure that the integrated intensity of the signal beam appearing in the recording area remains substantially constant. One embodiment of the control means which may be used to obtain this effect comprises a ceramic Piezo-electric transducer (26), Fig. 2 (not shown) having the mirror mounted thereon. In another embodiment, Fig. 3 (not shown) a mirror (14<SP>1</SP>) is in the form of an aluminium reflecting film supported on an elastic diaphragm (32) which is vibrated to smear the grating pattern.
